  • Fungi are usually heterotrophs meaning they derive their energy from other organisms.
  • They ingest their food through the process of absorption.
    • Small organic molecules are absorbed from the surrounding environment.
    • They digest their food outside their body by secreting powerful hydrolytic enzymes into the food.
    • These enzymes decompose complex molecules to the simply compounds that can be absorbed.
  • Their aborptive mode of nutrition seperates the fungi into 3 distinct types:
    • Saprobic - Energy from nonliving organic material such as dead things.
    • Parasitic - Energy from cells of living host.
    • Mutualistic - Energy from another organism, however they reciprocate with function. Meaning it is beneficial for both.
